"They were kissing at the sunglass rack in the men's section," an eyewitness told Page Six. A photo of the twosome ice skating with a pal was also posted on Twitter that same day, and Brent attended Berkus' book signing for The Things That Matter at Bergdorfs.
"So proud [of] Nate Berkus. Beautiful evening promoting truth, love and education http://www.tylerclementi.org. Love is love," Brent tweeted Tuesday.
Berkus was previously in a long-term relationship with Brian Atwood from 2007 to 2009. When Atwood became engaged to Dr. Jake Deutsch in August 2011, Berkus told Us, "We are still in touch and I am really, really happy for him."
